Laravel 6 在注册过程中生成用户名

Question

我不知道这是否可行。我创建了一个 Laravel 6 项目并添加了 auth。现在我希望程序在注册过程中生成一个用户名。用户没有任何输入字段来写他们的用户名。该程序应自动生成。例如，用户名是“test”，用户名可以是test12345678。基本上，它将是用户名 + 8 个随机数。这是 register.blade.php

这是 registerController.php:

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\User;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::HOME;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'avatar' => 'default.png',
        ]);        
    }
}

我还在用户 table 中添加了一个名为“用户名”的新列

Answer 1

您可以将以下内容添加到 RegisterController 上 create 方法中的 User::create 调用。

'username' => $data['name'] . rand(pow(10, 8 - 1), pow(10, 8) -1);

这将采用他们提供的名称并附加 8 个随机数字。

不要忘记将 username 添加到 User 模型上的 $fillable 属性。

protected $fillable = ['name', 'email', 'password', 'avatar', 'username'];

Answer 2

您可以在 RegisterController 中执行此操作，如下所示

/**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'username' => $data['name'] . str_pad(mt_rand(1,99999999),8,'0',STR_PAD_LEFT)
            'avatar' => 'default.png',
        ]);        
    }
